Topshelf一个用于使用.NET构建Windows服务框架
2 使用 2.1 创建应用程序首先，创建一个新的控制台应用程序并从nuget获取Topshelf和Microsoft.Extensions.Hosting软件包
Topshelf Microsoft.Extensions.Hosting当然我们也需要安装Serilog相关的日志框架。
Serilog.Extensions.Hosting Serilog.Settings.Configuration Serilog.Sinks.Console Serilog.Sinks.File Topshelf.Serilog 2.2 创建.NET泛型主机然后，我们先建立CreateHostBuilder()方法，并加载了Serilog日志并依赖注入MyService和AppSettings，MyService类做为Topshelf所使用的主要逻辑程序，它会提供Start()和Stop()做为Topshelf执行或停止主要逻辑程序的动作。
class Program { static void Main(string[] args) { var host = CreateHostBuilder(args).Build(); } public static IHostBuilder CreateHostBuilder(string[] args) => Microsoft.Extensions.Hosting.Host.CreateDefaultBuilder(args) .UseSerilog() .ConfigureServices((hostContext, services) => { services.Configure<AppSettings>(hostContext.Configuration); services.AddTransient<MyService>(); }); } 2.3 在Topshelf中注册服务接着，在Topshelf中注册我们的服务类。跳转到Program.cs并添加：
class Program { static void Main(string[] args) { var host = CreateHostBuilder(args).Build(); RunWindowsServiceWithHost(host); } private static void RunWindowsServiceWithHost(IHost host) { var rc = HostFactory.Run(x => { x.UseSerilog(); x.SetDisplayName("我的服务"); x.SetDescription("我的服务详细描述"); x.SetServiceName("MyService"); var myService = host.Services.GetRequiredService<MyService>(); x.Service<MyService>(s => { s.ConstructUsing(() => myService); s.WhenStarted(tc => tc.Start()); s.WhenStopped(tc => tc.Stop()); }); x.RunAsLocalSystem(); x.StartAutomatically(); }); var exitCode = (int)Convert.ChangeType(rc, rc.GetTypeCode()); Environment.ExitCode = exitCode; } } 2.4 MyService类接着，我们看看MyService类，主要演示了注入ILogger和AppSettings。
public class MyService { private readonly ILogger logger; private readonly AppSettings settings; public MyService(IOptions<AppSettings> settings, ILogger<MyService> logger) { this.settings = settings.Value; this.logger = logger; } public void Start() { logger.LogInformation($"Starting {this.settings.ServiceName}..."); } public void Stop() { logger.LogInformation($"Stopping {this.settings.ServiceName}..."); } } 2.5 运行应用程序最后，F5执行应用程序，如果一切顺利，你应该会看到类似以下内容的信息：
